     --
     -- A Frame Relay service is a multiplexing service.  Data
     -- Link Connection Identifiers enumerate virtual circuits
     -- (permanent or dynamic) which are layered onto the underlying
     -- circuit, represented by ifEntry.  Therefore, each of the entries
     -- in the Standard MIB's Interface Table with an IfType of
     -- Frame Relay represents a Q.922 interface.  Zero or more
     -- virtual circuits are layered onto this interface and provide
     -- interconnection with various remote destinations.
     -- Each such virtual circuit is represented by an entry in the
     -- circuit table.  The management virtual circuit (i.e. DLCI 0)
     -- is a virtual circuit by this definition and will be represented
     -- with an entry in the circuit table.

            'invalid' for some arbitrary length of time.  It is
            also legal to set the state of a virtual circuit to
            'inactive' to temporarily disable a given circuit.
